CVE-2026-35034
Jellyfin is an open source self hosted media server. Versions prior to 10.11.7 contain a denial of service vulnerability in the SyncPlay group creation endpoint (POST /SyncPlay/New), where an authenticated user can create groups with names of unlimited size due to insufficient input validation. By sending large payloads combined with arbitrary group IDs, an attacker can lock out the endpoint for other clients attempting to join SyncPlay groups and significantly increase the memory usage of the Jellyfin process, potentially leading to an out-of-memory crash. This issue has been fixed in version 10.11.7.

Versiones anteriores a la 10.11.7 contienen una vulnerabilidad de denegación de servicio en el endpoint de creación de grupos de SyncPlay (POST /SyncPlay/New), donde un usuario autenticado puede crear grupos con nombres de tamaño ilimitado debido a una validación de entrada insuficiente. Al enviar grandes cargas útiles combinadas con IDs de grupo arbitrarios, un atacante puede bloquear el endpoint para otros clientes que intentan unirse a grupos de SyncPlay y aumentar significativamente el uso de memoria del proceso de Jellyfin, lo que podría llevar a un fallo por falta de memoria.
